IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 72.589, dated December 24, 1867.

To all whom it may concern:

Be it known that I, HENRY BEEBE, of Hudson City, in the county of Hudson 'and State of New Jersey, have invented certain new and useful Improvements in Lanterns; and I do hereby declare that the following is a full, clear, and exact descriptionof the same, reference being had to the accompanying drawing, making a portion of this specification, in*

Figure l is a side view of a lantern constructed according to my invention. Fig. 2 is a vertical transverse section of the same.

Similar letters of reference indicate corresponding parts in both figures.

The object of this invention is to provide a lantern in which the flame will be so protected from currents of air that the lantern may be carried or moved without detriment to the steadiness andbrilliancy of the aforesaid llame thereof.

The invention consists in the combination, with the glass body of the lantern, of a metallic top provided with openings and lined with suitable reticulated material, whereby the formation of currents within the lantern by the irregular escape of the gaseousproducts of combustion therefrom is effectually provided against.

The invention further consists in a metallic base fitted upon the glass body just mentioned, and provided with lateral openings and an annular shield, in combination with the reticulated top plate and perforated sides of the burner, whereby the entrance of air in irregular currents to the iiame is prevented.

The invention further consists in a novel combination of parts, whereby'the more efficient operation of the two features just hereinbefore mentioned of the invention is secured.

To enable othersA to understand the nature and construction of my invention, I will proceed to describe it with reference to the drawings.

The oilreceptacle of the burner of the lantern is shown at A, and the burner itself at B; The sides of the upper part of this burner are formed with openings a, covered with perforated sheet metal, ait, or equivalent reticulated material, as represented in Fig. 2, the said burner being furthermore furnished with a top plate, b, through which extends the wick-tube 0*. O indicates the glass body of the lantern, which may be of any suitable form, and which has attached to it an annular base, D, which, when the lantern is ready for use, is placed upon or around the sides of the burner just described, and which isv provided with openings, a', which, when the base surrounds the sides of the burner, as just mentioned, are coincident with the openings a of the said sides. Attached to the outer side of the base D, and at a slight distance therefrom, is an annular shield, E, which extends downward below the openings a a' in such manner that a current of air passing toward theburner will be intercepted and turned aside by the aforesaid shield at the same time that air may pass freely through the openings a a', and up through the reticulated top plate to the dame at the upper end of the wick-tube, the reticulated material through which the air is thus caused to pass breaking the force of any irregular current that may pass up between the shield and the sides of the burner, so that by these means the passage of air in irregular currents to the ame is securely guarded against, and any liability of detriment to the flamefrom this cause, when the lantern is carried or swung, is prevented. Fixed upon the upper end of the body O is a metallic top, Ei, made preferably of a somewhat tapering form, and with its upper end perforated with numerous small holes, or, if preferred, with an opening covered with reticulated material. The sides of this top are a provided with numerous openings, b', and are lined with reticulated material, as shown at c.

As the gaseous products of combustion rise from the ii-ame they pass out freely through the reticulated material c and through the openings b', and also, to some extent, through the perforated upper end of the top Et, while any irregular currents of air thrown against the aforesaid top will have their force broken or moderated by the reticulated material to such an extent that they cannot affect the comparatively still condition of the air within the lantern. Furthermore, any irregular exhaustion or drain of the air or gaseous products of combustion from the lantern, which might otherwise occur by currents of air passing the same, is prevented by the resistance offered to such sudden outward passage of the air or gaseous products by the reticulated lining by which the openings b' are closed7 the lantern being thus enabled to be carried or moved Without detriment to the steadiness thereof.

When the lantern is employed Where no eur- Ients of air may be anticipated-as, forinstance, iu a room or apartment-the base D may be lifted or raised to such an extent as to bring the openings a. thereof above the top-plate, D, to permit the air to pass therethrough directly to the ame, the friction between the base and the sides of the burner being sufficient to hold the base in the aforesaid raised position.

That I claim as my invention, and desire l to secure by Letters Patent7 is- 1. The metallic top furnished with openings b' and lined with reticulated material c, in combination With the glass body C, substantially as and for the purpose spec-ined.

HENRY BEEBE.
